IMPROVEMENT IN HAY-DERRICKS.

To all whom it may concern Be it known that I, ALBEN BARNES, of Bloomington, in the county of McLean and State of Illinois, have invented a new and useful Improved Hay- Deirick; and I do hereby declare the following to bea full, clear, and exact description thereof, which will enable others skilled in the art to which my invention appertains to make and use the-same, reference being had to the accompanying drawings forming part oftliisspeciiication, in which- Figure l is a perspective view of my improved hayvderrick, and

Figure 2 is a plan view of the same, showing the lsweep removed. l

Similar. letters of reference indicate corresponding parts in the several figures of the drawings. i

My invention relates to that class of hay-derricks by which the hay is elevatedand swung over upon the load or stack by the same power, and has for its object t0 improve the construction of the same, whereby it shall be more'simple and perfect in its operation, as will be hereinafter more fully described.

In the accompanying drawings- A is the rectangular or quadlangular bed or base of the derrick, which supports the operating parts.

B is an inclined post, aiixed at its lower end to one side ofthe bed A, and held in position by means of the inclined ,braces C C affixed to the opposite side of the bed frame, as shown.

The upper end of. the post is hinged, as shown at D, to the upright E, whose lower end is pivoted to or stepped in the cross-bar A of the bed-frame.

In order to hold the upright E in a vertical position, it is necessary that the post B be inclined at such an angle that its upper end shall be in aline perpendicular -to Y the center of the cross-bar A ofthe bed-frame, as shown in fig. 2.

The upper end of the upright E is provided with the derrick-arm F, extending upon each side of the same, and held rmly imposition from the upright bymeans of the brace G. Firmly secured to the lower end of the upright, in such a manner as to turn with it, is a horizontal wheel, H, provided with pins a, around which passes the swinging or turning rope b. This rope, one end being rst fastened to one side of the wheel, as qshown at c, fig. 1, passes around the wheel in contact with the pins (t, and thence through an eye, d, affixed to one of the braces G to the whifletree I. Instead of being attached directly to the whitlletree, it may be secured to theelevating rope f, as shown in tlg. 1. This latter rope, one endbeing attached to the whiiletree, passes through an eye, g, affixed to the frame, and thence to the derrick-arm, along the under side of which it passes through eyes l1., the upright E,

and brace G to the hay or other weight to be elevated.

The operation of my improved hay-derrick is as follows:

` Power being applied to the whiletree I, the rope f is pulled in the direction of the arrow, iig. 1, and raises the hay K from the ground. When sufficiently elevated to be swung over the load or stack, the continued pull upon the rope f brings the swinging rope b into operation, which, acting upon the wheel Il, turns the same to swing the hay in the direction of' the arrow 2, over the load or stack, upon which it may be dumped by any suitable means.

The swinging rope remains slack or unstrained until the elevating rope has raised the hay to the proper height to be swung over upon the load,I when it is brought into operation to swing the derrick, as previously described.

The swinging movement of the derrick is limited, by means of a cord or chain, L', connecting the wheel I-I with the base A, as `clearly shown in iig. 2.

Having thus described my invention,

What I claim as new, and desire to secure by Lctters Patent, is-

The improved hay-derrick, consisting of the base A, inclined post B, inclined braces C, pivoted and hinged upright E, arm F, wheel H, having pins a, the

elevating and -swinging ropes f I), and the stop rope k, all constructed, arranged, and operating as herein shown and described.
